Altair 7x2 Inch XL Electronic Filter Wheel EFW

Product Description

The Altair Electronic Filter Wheel EFW holds 7x 2" astronomy filters and is driven by a precision stepper motor with accurate positioning system.

Only 20mm thick! Note: Baader filters will not fit because they are too tall. Altair and most other filters fit perfectly. (Baader filters can be rehoused in blank cells to fit).

USB Power - only one cable required for data and power!

CNC machined from a single piece of aluminium. A light trap machined into halves to stop stray light entering the filter wheel housing. Motor is not exposed therefore light cannot enter through the gap between motor and housing.

Supports interchangeable carousels amongst Altair XL size filter wheels.

7x36mm filter wheel and carousel include the required filter masks and screws to capture and hold 36mm unmounted filters precisely.

Includes a set of adaptors and spacers enabling out of the box use with most astro cameras including the Altair Hypercam.
